- The t-High setting allows for sustained lung recruitment, improving gas exchange by increasing alveolar surface area.
- To maintain maximal recruitment the t-High should be set at ~ 85% of the total cycle time.
Notice the above image with an appropriate set prolonged t-High, thus allowing for the majority of the breath phase to be devoted to alveolar recruitment.
Time Setting
- The recommended initial t-High setting in adults is 4-6 seconds.
- Pediatrics from 3-5 seconds.
- Neonates 2-3 seconds.
